Benefits of technology
The present invention is about a navigation system that helps drivers save fuel by using information on transportation, fuel efficiency, and geography to direct the vehicle to its destination quickly. The system can inform the driver of multiple routes, one of which may have excellent average vehicle speed and another may have excellent fuel efficiency. The driver can then select which route to take. The invention allows for more efficient driving and reduces carbon dioxide emissions, which is beneficial for the environment.
Problems solved by technology
One disadvantage of conventional navigation systems for vehicles is that it provides vehicles with navigation information irrespective of road types.
The problem is that a conventional navigation system has difficulty in reflecting such a difference in moving speeds of the vehicle to a navigation process.
As a result, it is impossible for the conventional navigation system to search for an accurate traveling path to a destination and to correctly calculate a fuel amount consumed in a corresponding section, such that it is unable to search for a route that minimizes the amount of fuel consumption.
Therefore, the vehicle navigation system for minimizing the amount of fuel consumption has a disadvantage in that it unexpectedly guides the vehicle driver to an undesirable traveling path incurring much more fuel consumption.
For example, assuming that there is a descent where decelerating of the vehicle is needed and an ascent where accelerating of the vehicle is needed, the conventional navigation system informs the vehicle driver of the ascent instead of the descent because it considers only the vehicle moving speed, resulting in much more fuel consumption.

Embodiment Construction
[0034]Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
[0035]FIG. 1 is a structural view illustrating an overall system including a navigation system (or a navigation server) for a vehicle according to an embodiment of the present invention.
[0036]The system shown in FIG. 1 includes a target vehicle 100, a navigation server 200, a geographical information server, a satellite 400 and a plurality of source vehicles 500.
[0037]In this case, a plurality of source vehicles 500 may represent vehicles located in a specific region. For example, a plurality of source vehicles 500 may represent vehicles located between subway station “A” to subway station “B”, moving in the direction of subway station “A”.
[0038]Each source vehicle 500 recognizes its own current position upon receivin...

A navigation system for a vehicle and a navigation method for the same are disclosed. The navigation system collects transportation information and fuel efficiency information from several source vehicles located in a specific region, generates an optimum route for the corresponding region, and informs a target vehicle having requested a navigation service of the optimum route, resulting in the implementation of more effective navigation service.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Korean patent application No. 10-2010-0059590 filed on Jun. 23, 2010, the disclosure of which is hereby incorporated in its entirety by reference.BACKGROUND OF THE INVENTION[0002]Embodiments of the present invention relate to a navigation system and a navigation service method for the same.[0003]A conventional navigation system for vehicles collects data including the moving speeds of vehicles located in individual regions in real time, and provides a user with a driving route along which a vehicle runs at the highest traveling speed, according to the vehicle traveling speed.[0004]One disadvantage of conventional navigation systems for vehicles is that it provides vehicles with navigation information irrespective of road types.[0005]For example, in a straight traffic lane, with a left-turn traffic lane, and a right-turn traffic lane at a crossroads, a vehicle generally moves at different moving speeds in...
